Anyone use a diablo tuner?

No fan in the world will cool the engine if you drive with the plow up. Just a few inches off the ground and tilt it to one side helps with air flow. Not perfect but it works. I plowed with dodges my whole life commercialy.

Also- when you put on the defroster- it turns on the ac electric fan. That also helps.
Tuners are great for helping with mileage, tire diameter changes and some even help with transmission shifting. Diablo is one of the better units I’ve used.
